How to take group photo?
Recently I took group photo and the outcome is pretty disappointing as the center is clear while the rest appears to be blur..

What should I do? Shoot at Aperture Priority mode with smaller aperture or ..?.

Please help, thanks!..

Can you post the picture so we can see it? If part of the picture is sharp and the rest is not, it suggests that the depth of field was too shallow and you need a narrower aperture. What settings (shutter speed / aperture) did you use?.

Thanks Mike..

What's the recommended value for the f/stop?..

Comment #2

What camera / lens do you use?.

On DSLR systems, apperture setting closer to medium (f5.6 to f/8) will be better. Lenses are best corrected in mid range. Full opened diaphragm shows corner distortion/softness on many defaul lenses. f/22 could be overall slightly soft in detail..

With PS cameras medium lens setting will be around f/4..

Semi closed diaphragm may require flash to acheve proper exposure. Bounce flash with diffuser will be best set..

The shot was taken with D80 and Sigma 18-200mm OS..

The group was about 3 meter in front and focal length is 44mm with f/4.8..

The aperture depends on how the people are assembled, what lens is in use, distances from camera to subject, and more..

When in doubt, f11 or 16..

The group was about 3 meter in front and focal length is 44mm with f/4.8.

In that case the depth of field should be from about 2.65 to 3.46 metres, i.e. everything in that range (about 40 cm either side of the focus point) should be in focus: see the depth of field calculator at.

If you had a group of people going back a long way and focussed on someone at the front, the back of the group could easily be out of focus. A person in the second row could easily be more than 46 cm behind the front row, and so slightly out of focus: and anyone in the third row (or behind) would be even more out of focus..

At f/11 in contrast the depth of field goes from 2.25 to 4.51 m. So if the front person was 3m away and you focussed on him/her, people 1.5 metres further back would still just be in focus..

Of course with a narrower aperture you need a slower shutter speed, and you have to be careful not to get camera shake (or motion blur because people are not standing exactly still). You need at least 1/60 second, preferably faster, at that focal length. If stopping the lens down to f/11 gives you a long shutter speed (say, 1/30 or 1/15 second) then increase the ISO setting on the camera until the shutter speed is fast enough. Or use a flash..

18-200mm f3.5 -6.3 OS will require strong external flash to work with f/8- f/11 to illuminate group of people indoors. Use of build-in flash will require higher ISO use 800 or 1600 that will show digital noise artifacts..

Get good external bounce flash and diffuser to get equaly lighted faces, and not worry about heavy shades..
